Fits the 6.7L Cummins in 2007-2010 Dodge full-size trucks and 2011-and-newer Ram 2500 / 3500 pickups. This is a direct bolt-in upgrade over the factory unit — same mount, same pulley position, no bracket modification.
Diesel engines spend most of their working life at low RPM, and that is exactly where a stock alternator runs out of headroom. This unit holds 200+ amps at engine idle and delivers a full 370+ amps at cruising speed, hot rated — enough for a lift pump, auxiliary lighting, a winch, a plow, a welder or a competition-grade stereo without watching your voltage sag at every stoplight.
Engine codes covered: 6.7L ISB
Vehicles: Dodge / Ram 2500 3500
This large case hairpin alternator offers the highest possible idle RPM output and durability available in a "direct bolt in" alternator. Featuring 6 phase technology and twin rectifiers, these alternators are totally durable for daily use, even in abusive applications. This alternator will make 200+ amps at idle, with 370+ amps at normal cruising speed. You won't find a more durable high output alternator anywhere!
